EV2483DQ-00C 4.5-55V, 2.5A Programmable Frequency White LED Driver Evaluation Board QFN3

The MPS EV2483DQ-00C is an evaluation board built around the MP2483 for bench characterisation of the device in its intended topology. It operates from a 4.5 V to 55 V input and is rated for 2.5 A. The board carries the device in its QFN3 package.

The MP2483 is a 55V, 2.5A, white LED driver suitable for either step-down or inverting step-up/down applications.

Design Notes

The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
